What a grand, impressive sight! This amazing A Night to Remember Staircase and Walls Kit creates an expansive decorative structure that is the perfect backdrop for your ballroom-themed Prom photo ops. The complete kit includes two walls that are mirror images of each other; both measure 8'3" high x 11'2" wide x 12" deep. The staircase is also included to display in between the walls; it measures 6'3" high x 9' wide x 52" deep. If arranged together, the total measurement is 25'3" wide! Both walls and the staircase are constructed of printed cardboard, cardboard tubes, and triangle supports. NOTE: These staircases are not designed to be walked upon. Assembly required.
